Introduction

　　Established in 1993, the ICU at Shenzhen Second People’s Hospital serves as the Vice Chair Unit of the Guangdong Society of Critical Care Medicine and the Chair Unit of the Shenzhen Society of Critical Care Medicine. It is recognized as a Guangdong Provincial High-Level Clinical Key Specialty. The department has introduced leading experts through Shenzhen’s “Three Renowned Programs,” including Professor Chen Dechang from Ruijin Hospital, the Chair of the Chinese Society of Critical Care Medicine, and Professor Cheng Shouzheng, Vice President of the Chinese Nursing Association and Chair of the Guangdong Nursing Association, from the First Affiliated Hospital of Sun Yat-sen University. Several department members hold national committee positions in critical care and emergency medicine-related societies. With over 30 million yuan in dedicated funding for specialty development and research, the department is a well-equipped clinical and training base for critical care medicine in Shenzhen, training hundreds of graduate students, trainees, resident physicians, and interns annually.

　　Specialty Features

　　The department operates 37 open beds within a 936.6 m² facility. It specializes in the diagnosis and treatment of conditions such as sepsis, septic shock, severe trauma, multiple organ dysfunction syndrome (MODS), acute fulminant myocarditis, cardiogenic shock, and critical care for pregnant and postpartum women. The team is proficient in mobile ICU operations and remote critical care using ECMO (Extracorporeal Membrane Oxygenation), mechanical ventilation, and multi-modal high-flow humidified oxygen therapy. Comprehensive cardiac and pulmonary rehabilitation programs are provided for critically ill patients, alongside advanced blood purification techniques, personalized venous and arterial access procedures, and nutritional support for critically ill individuals. The ICU is equipped with state-of-the-art precision instruments and devices, ensuring comprehensive monitoring and treatment for the most complex and severe cases. It primarily admits patients suffering from various types of shock, respiratory and circulatory failure, cardiopulmonary resuscitation, disseminated intravascular coagulation (DIC), acute respiratory distress syndrome (ARDS), severe infections, multiple organ dysfunction and failure, severe trauma, and postoperative recovery and monitoring following major surgeries.

　　Research and Achievements

　　In recent years, the department has made significant advances in research, including whole-genome sequencing for pathogen detection in sepsis, molecular mechanisms of hemorrhagic shock and acute hypoxic kidney injury, single-cell sequencing in septic patients, and clinical applications of novel inflammatory markers for sepsis. The department has also developed multi-parameter modeling for sepsis diagnosis and treatment, as well as conducting clinical studies on high-flow humidified oxygen therapy for artificial airways. These efforts have established a distinct academic and clinical specialty in critical care medicine. The department admits approximately 1,000 inpatients annually, with 98.86% of cases classified as CD-level critical illnesses.
